We noticed this years ago when looking at -- IIRC -- ikaros antibodies. They were clearly faked. Lacking any sort of platform to gain attention we moved on to Abcam and our lab just sort of maintained a mental map of who not to purchase ANYTHING immuno- from.

it's quintessential hacker news though to complain relentlessly about something and then never adopt an alternative. how dare you do the right thing and use somebody else!
